Show answer and explanation

Correct answer: (B) Fewer scores have low values than have high values; (D) More scores have high values than have low values

Explanation

In a left-skewed distribution the long tail is on the low side and most scores bunch up at the high end, so fewer scores have low values than high values (B and D say the same thing).
